Specification of Letters Patent.

Patented Feb. 29, 191 6.

To all whom it may concern Be it known that I, WILLIAM J. COLE- BOURN, acitizen of the United States, residing at Louisville, in the county of Jefferson and State of Kentucky, have invented cerq tain new and usefulImprovements in Dumping-Wagons, of which the following is aspecification, reference being had therein to the accompanying drawing.

- This invention relates to dumping wagons. The best known type ofdumping wagons has downwardly swinging bottom doors closed.

. which they carry.

The principal 0b ect of mv invention is to provide a winding drum ofthis character with a pawl and ratchet actuating mechanism in which thepawl will be automaticallv moved out of engagement with the ratchetwheel at the end of the winding operation, and will be moved intooperative engagement with said wheel when the operu thereof out ofengagement with the ratchet ato-r grasps the operating device.

Another obiect of the invention is to p o- '1 vide a yielding detentpawl to hold the the same as applied to one side of the goose-f neck 5of the body 6 of a dumping wagon with said wheel.

drum against rotation in a reverse direction when the operating pawl hasbeen moved out of engagement therewith, and to pro-ji vide such detentwith a tripping lever which may be locked against movement in adirec-gs;

ment of the drum 9 1n a reverse direction. drawing the figure is aperspective view of the forward end of; a dumping wa on showing theapplication, of a door actuating mechanism showing one;

{i this pawl'is formed with a nose 23 for ention to trip the detent.

In the ac zompanying embodiment of my invention.

bodiment of my invention and have shown which is provided withdownwardly swinging bottom doors 7-7; these doors being connected bymeans of chains 8-8 or other carried by a shaft 10 that is journaled ina frame 5 between the sides of the gooseneck 5.

Winding movement is imparted to the drum 9 preferably by an operatinglever 11 which is loose on the shaft 10 adjacent one end thereof. Fixedon the shaft 10 adjacent the lever 11 is a ratchet wheel 12 and a pawl13- is pivoted intermediate its ends to the lever 11 and has its tailportion weighted, as at 14-, to cause the nose 15 of said pawl to benormally held out of engagement with said ratchet wheel 12. The pawl 13is preferably moved into operative engagement with the ratchet by theact of the operator in grasping the hand grip on the operating lever 11.To this end a bell crank handle 16 is fulcrumed at its angle, as at 17,adjacent the hand grip of the operating lever. The lateral arm of thehandle 16 and the tail of the pawl 13 are pivotally connected by a rod18. It will thus be observed that when the operator grasps the operatinglever 11 he presses the handle 16 in a direction toward the lever and asa result the nose 15 of the pawl is engaged with the ratchet 12. It isalso to be noted that upon the release of the handle 16 by the operatorthe weighted end 14: of the pawl will lift the nose 15 12 andsimultaneously return the handle 16 to its initial position.

I Attached to the side of the goose-neck 5 in advance of the ratchet 12is a plate 19, the rear end of the plate being formed with a laterallyextending bearing 20. A suitable detent is provided to prevent themoveand. in the present instance, this detent is in the form of a'pawl:21 which is disposed "within and pivoted intermediate its ends, 'as at22, to the bearing 20. The rear end of 'gagement with the teeth of theratchet 12 and the forward end of said pawl is enlarged as at 24:. toform a weighted end to yieldablv hold the nose 23 in engagement hen thenose 23 is in engagement with the ratchet wheel, the wheel, because ofthe tendency of the drum ,1 suitable: flexibleoonneotionst with; adrum9mm unwind causes a direct longitudinal pressure upon the detent, and asa result, the beveled end of the nose is wedged between adjacent teethof the ratchet. This wedging action tends to prevent the pawl from beingeasily disengaged from the ratchet. Therefore in order to overcome thisvobjection, the nose is formed with a break joint as indicated by thenumeral 23 this joint permitting the pawl to break before becomingdisengaged from the ratchet.

In order to trip the pawl 21 to release the drum 9 and the dumping doors7 a suitable tripping device is provided and is here shown as a footlever 25 which is pivotally mounted adjacent its rear end upon a bolt26, carried by a bracket 27 which extends from the plate 19. The rear orshort arm of this lever is disposed under the weighted end 24 of thedetent 21 and is correspondingly curved to receive said end 24. Theopposite or forward end of this lever eX- tends through a suitable guide28 which is attached to the side of the goose-neck 5 and terminates inadvance of said guide in a laterallv evtending foot piece 29.

' A. suitable locking device is provided to support the weight of thelonger end of the lever 25 and to consequently prevent the accidentaldisplacement of the detent 21. This locking device comprises a latch 30which is pivotally connected at one end. as at 31, to the side of thegoose-neck 5. This latch includes a laterally extending hand piece 32which is arranged to be disposed under the longer arm of the foot lever25 and to co operate therewith to prevent downward movement of thelever.

In passing over rough roads there is a tendency of the detent 21 tobecome accidentally disengaged from the ratchet wheel 12. and in orderto positively lock this detent against such movement. a locking lever 33is fulcrumed upon the bolt 26, and this lever is formed with a stopshoulder 34, which is adapted, when the lever is moved rearwardly, toengage over the tail 24 of the detent 21. In this position of thelocking lever 33. the shoulder also prevents the tripping device fromperforming its function of releasing the detent 21.

In operation when it is desired to dump the wagon. the stop shoulder 34of the lever 33 is first disengaged from the tail 24 of the detent 21 byswinging said lever forwardly, and the locking detent 30 is swung uponits pivot 31 from its engagement with the foot lever 25 by the fingerpiece 32. The operator then depresses the foot lever 25, and as aresult, the shorter arm thereof elevates the tail or weighted end 24 ofthe detent 21, thereby breaking the joint 23 of said detent anddisengaging the nose 23 thereof from the ratchet wheel 12. This permitsthe drum 9 toreadily revolve and consequently unwind the chains 8. "Whenit isdesired to close the doors 7 the detent 30 is returned to itslocking position with respect to the foot lever 25. The operatingleverll is oscillated and, as a result, the ncse 15 of the pawl 13 willalternately engage and ride over the teeth of the ratchet wheel 12,thereby rewinding the drum 9. At the same time the nose 23 of the detent21 will slide over the teeth of the ratchet 12 and will serve to locksaid wheel against reverse rotation when the operating lever 11 is swungrear-v wardly. After the doors 7 have been closed the lever 33 is'movedrearwardly and, as a result, the detent 21 will be securely locked inengagement with the ratchet wheel 12.

While I have shown and described one embodiment of my invention it willbe understood that this has been chosen for the purposes of illustrationonly and that I do not desire to be limited to the details ofconstruction shown and described, for obvious modifications will occurto a person skilled in the art.

Having thus fully described my inven tion, what I claim as new anddesire to secure by Letters Patent, is
